An improved strategy to analyse strigolactones in complex sample matrices using UHPLC–MS/MS

Plant Methods, 2020
Background Strigolactones represent the most recently described group of plant hormones involved in many aspects of plant growth regulation. Simultaneously, root exuded strigolactones mediate rhizosphere signaling towards beneficial arbuscular ...

Artificial Seed Production from Encapsulated Microshoots of Cauliflower (Brassica oleraceae var botrytis) [PDF]

, 2012
A cost effective protocol for the production of cauliflower microshoots suitable for encapsulation was designed. Microshoots were encapsulated in sodium chloride matrices. The use of 2% of sodium alginate and 15 g/L of dehydrate calcium chloride produced

Dual Role of Gibberellin in Perennial Shoot Branching: Inhibition and Activation

Frontiers in Plant Science, 2020
Shoot branching from axillary buds (AXBs) is regulated by a network of inhibitory and promotive forces, which includes hormones. In perennials, the dwarfed stature of the embryonic shoot inside AXBs is indicative of gibberellin (GA) deficiency ...

The Cytokinin Status of the Epidermis Regulates Aspects of Vegetative and Reproductive Development in Arabidopsis thaliana

Frontiers in Plant Science, 2021
The epidermal cell layer of plants has important functions in regulating plant growth and development. We have studied the impact of an altered epidermal cytokinin metabolism on Arabidopsis shoot development.
